To all whom 'it may concern:

Be it known that I, OMER DUIs, a citizen of the United States, residing at Streator, in the county of La Salle and State of Illinois, have invented a new and useful Moisture- Supplying Device for Carbureted Air, of which the following is a specification.

The present invention relates to improvements in moisture supplying devices for can bureted air, the primary object of the invention being the provision of a device adapted to be interposed between the carbureter and the intake manifold of an explosive engine and supply a spray of vapor from a main water supply in a ve1l from circumferential points at the junction between the carbureter and the manifold, whereby the carbureted air formed by the carbureter and atits entrance to the manifold will be properly saturated with such moisture or vapor to provide a carbureted air that will not prematurely explode during the compression thereof in the engine cylinder, and at the same time provide a carbureted air that during the admission and explosion thereof will not so entirely consume the lubricating oil within the cylinder as to produce the undesirable residue or carbonization of the cylinder and piston.

A further object of the present invention is the provision of a moisture supplying nozzle adapted to be disposed as a connection between the carbureter and the intake manifold of an explosive engine, the same having an annular channel with an annular opening, whereby the veil of moisture is sprayed from various points throughout the clrcumference of such device toward the center, whereby the carbureted air entering the manifold will be thoroughly saturated as the same passes through the veil of moisture or vapor thus projected.

A still further object of the present invention is the provision of a moisture supplying device disposed at the junction of a carbureter and manifold, the said carbureter being provided with the usual throttle, while the said device for supplying the moisture with carbnreted air after leaving the carbureter and before entering the manifold, is provided with acontrol valve which is connected inoperable relation to the throttle valve of the carbureter, whereby the supply of moisture to the carbureters will be commensurate, or in proportion, to the carbureted air supplied to the manifold.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 is a sideelevation of a carburetor and the lower portion of a manifold with the moisture supplying device in operable relation thereto. Fig. 2 is a top plan view of the lower member of the moisture supplying device. Fig. 3 is a bottom plan view of the upper member of said moisture supplying device. Fig. 4: is a section taken on line 4-4 of Fig. 1; Fig. 5 is a detail view. of the valve for controlling the carbureter, said manifold as is usual leading to an explosive en ine (not shown). The carbureter is provi ed with a usual throttle valve 4 whichis operably connected to a crank arm 5 to. which is connected a rod 6,

the same to be operated simultaneously with I ing medium therebetween, the same being made in the same contour. as said flanges and consisting of the lower member 9 and the upper member 10, both of which are provided with apertures A through which the. carbureted air passing from the carbureter C may enter into the lower end of'the manifoldS.

Mounted between the adjacent faces of the members 9 and 10 of the moisture sup plying device D, is a thin gasket 11, while formed in the inner face of the member 9 adjacent to the inner face of the member 10, and about the aperture A, is an annular channel 12, whose edge 1.3 in combination with the gasket 11 provides the annular or circular outlet 14 for the channel 12 and consequently a spraying nozzle at the junction between the members 9 and 10 of the moisture supplying device D.

Formed integral with the lower member of the moisture supplying device D is a lug 15 which 'has connected thereto, the valve casing 16, said valve casin being interposed between the said pro ection 15 and the water supplying pipe 17, which receives its water from any means, preferably a tank (not shown). Formed in the projection 15 is the water inlet channel 18 which terminates in the outlet 19, so that the water led from the conduit or pipe 17 to the valve casing 16 and channel 18 will enter into the annular channel 12 of the member 9 and as the opening or nozzle 13 between the respective mem 'ers 9-, and 10, is so minute, a

veil of vapor or moisture is sprayed inwardly from all points of the circumference of the aperture A of the moisture spraying device D, so that a veil of vapor or moisture is formed across the aperture A so that any carbureted air passing from the carbureter G into the manifold 3, will pass through the said veil of vapor ormoisture and cause the 7 said moisture to be thoroughly commingled with the carbureted air, thus saturating the carbureted air with moisture before the same is conducted into the manifold 3 and finally into the'engine (not shown).

The valve 20 mounted in the valve casing 16 is made in the usual truncated conical shape as clearly shown in Figs. 5 and 6 but in the present instance is provided in addition to the main port or channel 21 with the end auxiliary-port 22, and the two reduced ports 23 and -24 respectively, all of said ports 22, 23 and 24 leading into the main port 21 as clearly illustrated in Fig. 6, and so disposedthat the supply of moisture from the pipe 17 to the channel 12, as the "alve 20 is first turned, will first enter the port 22 pass through the port 21 and the first reduced port 23 and thus enter the channel 18 in a greatly reduced stream. A further movement of the valve 20 will bring the port 24 into alinement with the channel 18 thusincreasing' the su ply of moisture to V108, or when thethe moisture supplying :of the throttle 4 to pass into the manifold 3.

In order to provide a simultaneous actuation of the throttle valve port 4 and the valve 20, the stem 25 of the valve 20 has connected thereto a crank 26, whose free end is connected to the rod 6 and consequently to the crank 5 of the throttle valve 4, so that the main throttle controlling rod 27, operated from any desired place, will move the crank 26 and valve 20 and simultaneously the throttle or throttle valve 4. By this means it will be seen that the supply of carbureted air to the manifold 3 and the supply of moisture to the moisture supplying device D are regulated to an exactness and in proportion to the amount of carbureted air supplied to the manifold 3.

From the foregoing description, taken in connection with the drawings, it is evident that a device of this character may be readily applied to any form of carl'mreter and at its junction with the manifold and that although shown as disposed in a horizontal position in the present instance, the same may be disposed at any angle but preferably adjacent to the outlet of the carbureter so as to produce the desired veil of vapor or moisture through which the carbureted air must pass before entrance to the manifold to thus thoroughly saturate the carbureted air with the proper quantity of water, thus providing an explosive mixture which will not prematurely explode due to the compression and heat in the engine and which will prevent to a great extent the carbonization of any oil, either the oil not properly mixed in the carbureted air or the lubricating oil within the cylinder. Further by reason of the peculiar form of valve for controlling the supply of moisture to the moisture supplying device, the said moisture may be regulated to an exactness and in the proper proportion to the amount of carbureted air bein formed and admitted through the manifold to the engine.
